The Persian Gulf state took delivery of £800 million ($1.14 billion) worth of BAE's Eurofighter Typhoon jet during 2015, boosting its airborne presence and the coffers of BAE. It is set to buy even more this year.

But it's not just British-made planes that Saudi Arabia buys. In fact, it has one of the best-funded defence forces in the Middle East.

It has been throwing its weight around recently, engaging in a war in Yemen and joining forces with Turkey against Syrian President Bashar Assad.

So here's what all that money has bought it:

The Typhoons built by BAE are a key part of Saudi Arabia's strong air force. It contains more than 300 fighter jets and 15 active airfields. The Typhoon is one of the most advanced jets ever built and was a joint project between members of the European Union.

Also included in Saudi Arabia's airborne fleet are dozens of US-made F-15s, with another 80 on order.

The Saudi air force will soon include 22 new Hawk Advanced Jet Trainer aircraft, which, like Typhoons, are built by BAE. Hawks, first flown in 1974, are used to train fighter pilots before they graduate. The Red Arrows, a British acrobatic flight squad, use Hawks.

Saudi Arabia also has more than 100,000 people in its national guard, which is used primarily to secure internal threats but has been used as an expeditionary force, too.

The military has 442 M1A2 Abrams tanks, produced in the US. The engines put out 1,500 horsepower and can run on any fuel. They are equipped with a 120 mm smoothbore gun, designed by Rheinmetall AG of Germany, capable of firing a variety of rounds. The tank also comes armed with machine guns.

Saudi Arabia has about 82 AH64D Apache helicopters — the most advanced multirole attack helicopter, according to its manufacturer, Boeing. The chopper can classify and prioritise 128 targets in less than a minute.
